Heat Transfer Analysis of Silver-water Nanofluid Flow over Stretching Cylinder Subjected to Multiple Convective Conditions over Stretching Sheet and Stretching Cylinder

Abstract

Tiny particles are essential in electronics, heat exchangers, nanotechnology, and materials science because of their exceptional thermal conductivity and unique properties. The study investigate the MHD flow over a stretching cylinder containing silver-water nanofluid in the presence of a magnetic field under multiple convective boundary conditions over stretching sheet and stretching cylinder. A system of PDEs is reduced to a solvable system of ODEs by applying a suitable similarity transformation. We employ the Runga Kutta method along with shooting procedure to solve the flow, heat, and mass transfer equations along with boundary conditions. The results obtained from MATLAB codes are compared with previously published results of the same nature in limiting case. In this model, we made a comparison between the stretching cylinder and a flat sheet and those are represented via graphically. Numerical results of skin-friction coefficient and local Nusselt are systematized in the form of tables for sheet and stretching cylinder. The plots illustrate the effect of different dimensionless parameters on velocity, temperature, and concentration profiles. Significant role of Biot number on temperature and concentration profile was observed. Nusselt number increases with Bi and Pr but decreases with M. The skin friction is enhanced with M but decrease with \(\lambda\)
